Boom boom boom!
The demonic beasts were too numerous, how many were there? It was impossible to see the end with a single glance. Fortunately, the strongest demonic beasts were only at the Innate level, which somewhat relieved Yang Feilong. The Yin-Yang Myriad Laws Divine Skill automatically circulated, replenishing the consumption of Yin-Yang energy!
Otherwise, he would have exerted too much force, resulting in great destructive power but not enough endurance.
A man who lacks endurance is not a true man!
"Boom!" "Boom!" "Boom!"
Yang Feilong wielded the top-grade spirit artifact, the Mountain Sea Sword. He did not unleash some of its core powers, but his attacks, amplified by the spirit artifact, had already seen a significant increase in power compared to normal circumstances.
Dealing with these great demons, most of whom were at most at the Innate realm, was incredibly easy. And with each use of the Mountain Sea Sword, Yang Feilong's connection to it grew even closer.
Although Yang Feilong had refined the Mountain Sea Sword before, it was only a preliminary refinement. The power he could wield was far from its limit.
If the top-grade spirit artifact, the Mountain Sea Sword, had a power of one hundred points, Yang Feilong had not even reached ten points yet.
These demons from the Demon Realm were from the lower strata, generally possessing low intelligence, and their combat was mostly based on instinct. However, even with instinct, they knew fear. At this moment, these demons were utterly terrified by Yang Feilong's frenzied slaughter.
They began to flee in all directions.
Yang Feilong did not pursue these demons because they were endless. He could kill himself trying and still not finish them all.
After all, the mortal world, Earth, had a population of over six billion. The Demon Realm, as one of the Three Thousand Great Worlds, likely harbored tens of trillions of demons!
Whether that was true or not, even if only a million demons came, Yang Feilong could not finish them. His Yin-Yang Myriad Laws Divine Skill could operate automatically, so he didn't need to worry about the consumption of Yin-Yang energy, but what about his mental strength? It would become fatigued.
And his physical body? It couldn't withstand it either!
Moreover, Yang Feilong could sense that in the mortal world, due to the scarcity of spirit artifacts, the operation of the Yin-Yang Myriad Laws Divine Skill could not fully compensate for the consumption. Furthermore, due to the deaths of numerous demons, the spiritual energy dispersed in the air was mixed with demonic qi.
A small amount was fine, but if it was too much, his body might be contaminated by the demonic qi, or even worse, excessive amounts could cause problems with his cultivation.
Therefore, the passage connecting the Demon Realm to the mortal world had to be sealed as soon as possible!
This way, demons would not continuously enter the mortal world through the passage. The demons that had already come would ultimately be rootless, and with some effort, they could all be annihilated!
Swish swish~~~
Yang Feilong's figure flickered, gradually moving towards the area with the largest concentration of demons.
In half an hour, how many demons had he killed? If not ten thousand, then at least seven or eight thousand.
At this point, Yang Feilong finally found the demon passage. Compared to the two passages in Baiyun Mountain before, this one seemed to be slightly larger in scale.
It was no wonder so many demons were coming through the passage!
If left unchecked, as more and more demons passed through, the demon passage would expand, and eventually, Golden Core level demons could pass through.
That scenario was unimaginable. Yang Feilong's current combat power was overwhelming against demons below the Golden Core level, but against Golden Core level demons, it was uncertain. Some powerful Golden Core level demons might even be beyond his match!
Unless Yang Feilong could also break through to the Golden Core realm. With his cultivation system that perfectly fused the three major cultivation paths, once he broke through to the Golden Core realm, he might be unrivaled below the Nascent Soul stage!
However, taking that step was clearly not easy.
Although Yang Feilong now had some inklings, he had not yet fully fused them. Therefore, Yang Feilong, in his current state, did not know how to take that step!
What he had to do next was to find a suitable path.
As Yang Feilong approached the entrance of the passage, he suddenly slashed out with his sword. Instantly, it was like the sky collapsing, covering an area of over a hundred meters. The thousands of demons within that hundred-meter radius were all engulfed.
Boom boom boom!
Like a great fire burning ants, all the demons within the covered area perished instantly!
He needed to set up a seal here, and naturally, he couldn't allow those demons to interfere. Then, Yang Feilong struck the demon passage with a sword. Immediately, piercing screams echoed from within the passage.
Clearly, there were still demons trying to pass through the demon passage, but they hadn't fully emerged yet!
This time, Yang Feilong directly intercepted and killed them within the passage.
Next, Yang Feilong casually set up a defensive formation around the area, mainly to prevent any demons from attacking him while he was setting up the seal!
After that, Yang Feilong set up a sealing formation at the exit and then descended into the passage. He placed a seal every so often, and in the blink of an eye, Yang Feilong had laid down a total of nine seals.
"This small world is quite vast!" Yang Feilong stood in a large space. This was a small world that had emerged between the mortal world and the Demon Realm. This small world would eventually merge into the Spirit Realm and become a part of it.
The Spirit Realm had been expanding all these years because of the continuous integration of numerous small worlds surrounding it.
Yang Feilong did not rush to collect the heavenly treasures and earthly materials within this small world, as there were still many demons outside to deal with. The more demons he killed, the less harm ordinary people in the mortal world would suffer.
Of course, one could also enter the Spirit Realm through here. Therefore, Yang Feilong set up multiple formations and seals.
Aside from himself, unless one possessed extraordinary strength or extraordinary formation skills, one could not break his seals.
......
Yang Feilong soon flew out of the demon passage and returned to the mortal world. He did not remove the defensive formation, but besides the formation, he began to continue his slaughter.
Meanwhile.
While Yang Feilong was searching for the demon passage, Murong Qingxue, leading the others, was slaughtering immense numbers of demons while heading towards the Witch Gu tribe.
"How many demons have come through the Demon Realm here?" Murong Qingxue exclaimed.
"If not a hundred thousand, then probably seventy to eighty thousand!" Luo Xiangning said with a grave expression.
"If so many demons successfully leave Wulong Mountain, how many people will die?" Xi Mengru's face showed worry. Some of these demons were beyond her ability to deal with, and the mortal world was mostly populated by ordinary people.
Ordinary people encountering these demons, even the weakest ones, would have no chance of survival!
"Therefore, the demon passage must be sealed. Only then can the root problem be solved!" Murong Qingxue said earnestly.
"Indeed!" everyone echoed.
After an unknown amount of time, their group finally arrived at the location of the Witch Gu tribe.
